Cops at the scene took four hours to take a look at the device, said to have included something resembling a timer, and clear the bus.

The suspect was arrested on suspicion of making terrorist threats (allegedly to the driver of the bus) and possessing a hoax device.

Not to be outdone, two or three travelers on a plane from L.A. to New York spooked flight staffers enough that two F-16 jets were scrambled to escort American Airlines flight 34 for 100 miles as it headed to John F. Kennedy International Airport and landed safely shortly after 4 p.m.

The problem?

It's not clear. Some reports indicated the two or three locked themselves in the bathroom and wouldn't come out. A mile-high menage a trois?

U.S. air marshals were reportedly on the plane and helped get the situation resolved.
